[graphviz-interest] Sizeing

I freely admit to not understanding the various (and many) parameters
that control sizing in graphviz, and how they interact.

Clearly (!!) ratio, ranksep, size, dpi, fontsize are all part of the mix.

My current practice is to allow graphviz (dot) as much space as it likes;
I then zoom down the final PDF/SVG to fit a page if neccessary; otherwise
I simply zoom the document using zoom mode.

One complicating factor may be that I use a list of "synthetic invisible"
nodes to ensure that all my boxes with the same date
lined up and are ordered.

However; In my attempts to draw family trees for genealogical purposes, I am
currently getting large distance between my boxes, and small unreadable text.

I am happy with the layouts I'm getting; it's purely the readability
that I feel could be better.

I attach a dot file; I use
  cat tree.dot  | dot  -Tsvg  > tree.svg

to process it;

my current dot version is
  dot - graphviz version 2.36.0 (20140111.2315)
